50 mph Motorways
Discussion
Found this on the BBC news site this morning. Apparently slower speed equals less traffic - must remember that next time I'm doing 4 mph on the M25 / M4.
Only good point is that an increase in limit to 80 mph is being considered 'at other sites'. That'll be a 1 mile stretch of the M6 by the RAC building in Birmingham on all days of the week without a 'd' in them then.

Could be worse. Apparently the optimum speed for maximum traffic flow is 17mph.
The bods who calculate this stuff seem to actually believe the stopping distances quoted in the Highway Code, and these are programmed in as part of the model. As speeds increase, so do distances between cars - inordinately so if the Highway Code is to be believed - and so the traffic volume decreases.
This is the theory behind the variable speed limits on the M25. Now if you make the speed limit 50, you get the benefits without the cost, and as a bonus you get more people speeding when the traffic flow is lighter, so what was a costly traffic management system now becomes an effective revenue stream! Whee-hey!
Anyone care to bet that this won't happen?
